pp WINDING- MACHINE.

srEciricA'rioN lforming part or Letters Patent No. 695,645, dated March 18, 1902.

Application filed .Tune 27, 18978.

To @Zlio/71,071?, t may concern:

Be it known that LALFRED BRYANT MORSE, of Boston, county of Suffolk, State ofMassachusetts, have invented an'Improvement in Winding-Machines, of which the following description, in connection with the accom'- panying drawings, is a specication, like let; ters on the drawings representing like parts.

My present invention is an improvement on thread Windingmachines, particularly those of the kind patented to me December l1, 1896, No. 572,309, and has for its object the production of a more compact and simpliied machine capable of a greater range of usefulness, increased economy in running, Y

and saving of power.

In my former machine the throw-cam is mounted on a shaft parallel to the main or driving shaft and having bearings in a swinging bracket.

In my present construction I havel done away entirely with much ofthe mechanism shown in my said patented winding-machine and have mounted the throw-cam directly on the main shaft, my invention also including the provision of a construct-ion which enables me to change the machine for winding a short cop or bobbin readily or a long one, as desired. Again, in my patent the machine requires a considerable alteration and readj ustment of parts to convertit from winding a cone to winding a parallel quill, and accordingly another object of my present invention is the provision of simpler means for chang-` ing from cone-winding to cylinder or parallel winding, or vice versa. l

Further improvements of my present invention will be more fully apprehended in the course of the following detailed description,.reference being had to the accompanyin g drawings, illustrative of the preferred embodiments thereof, and the invention will be more particularly defined in the appended claims. l Y

ferent forms of thread masses. Fig. 3 is a right hand end elevation of the machine shown in Fig. 1. tivelyfviews in central longitudinal section and. end elevation of a detail'of construction.

In suitable standards ct a I journal a main .shaft b, herein shown as provided with usual fast and loose pulleys h b2, driven from a beltl h3. Between the standards and loosely journaled on the main or driving shaft b between collars c 'c' is a throw-cam d, herein shown as having its hub d reduced, as indicated by dotted lines at d2, to receive a driving-gear e, secured thereto by means of a set-screw e.

The shaft b is provided with a suitable speed-changingdevice, herein shown as composed of cones ff', belt f2, and beltshifter f?, all of any usual or preferred kind for suitably changing the speed to correspond to different requirements of the Work. The pulleyf is mounted on a stub counter-shaft journaled in the standard a and provided at its opposite end with apinion g,

meshing with'an` intermediate gear or idler` g', geared in turn to the driving-geare of the throw-cam, itbeing understood that the train of gear as thus arranged is provided for convenience in drivingthe throw-cam, it being Figs. 4 and 5 are respecpreferable that the latter should rotate in the same direction as the Vmain shaft.

Loosely mounted on a fixed sleeve surrounding the shaft b between the standard c and a collar c2 is a bracket 7i, having an extended hub h and splitat its upper end to receive a spindle t', held in clamped position by a bolt h2, this spindle being provided at its upper end with bearings t" i2, carried by a yoke 3, rigidwith said spindle. In said bearings t" 2 is journaled the quill-spindle 7c, having a gear 7c fast thereon between the bearings 'i' 'i2 and driven from a gear la?, fast on the main shaft, through an intervening idler 7c3,"jour naled at 7.34 in the bracket h.

The quill-spindle kis held in proper position adjacent the thread-guide m by means of a weight w,suspended from an :arm w', extending rearwardly from the hub-h', Fig. 3.

In my patent .above referred to I'provided.

a compound swinging movement, both the quill-spindle and the thread-guide swinging together; but in my present invention Ihave arranged the thread-guide m lto reciprocate in a stationary bearing, it being herein shown in the form of an arm carried by a thin tube on', Fig. 4, mounted on a rod m2, fast in the frame of the machine, said tube being provided with a stud or roll m3, traveling in the path of the throw-cam, and having an opposite lug m, traveling in a slot or way m5 in the frame of the machine for maintaining the proper direction of movement and keeping the thread-guide steady and uniform in its operations.

It will be understood that the reciprocations of the thread bar and guide are exceedingly rapid, and therefore it is of considerable importance that these parts should be as light as possible. They m ust, however, have great strength to accomplish the excessive work required of them. I have attained these objects by making the tube m of thin drawn tubing, which being cylindrical is capable of withstanding great endwise strain without buckling, and in order to insure that the strain shall be endwise without any twisting or buckling tendency I support the tube m at its ends on annuli m6, which fits snugly onthe rod m2, and not only therefore accurately center the guide-bar, but give a friction bearing-surface and leave an internal air-space of considerable extent between the tube and the rod, which materially aids in reducing the friction, and outside of the annuli m6 I shrink on the encompassingthread-guide m at one end and a ring at the other end, carrying the stud 'm3 and lug mi, so that the ends of the tube m are pinched immovably between the thread-guide and one annuius m6 at one end and between the stud-support and the other annulus mf at the other end.

The thread, twine, or other material t bcing wound passes from any usual source over rolls p p', as in my patent, and thence to a tension-wheel p2 and other tension meehanism, the same as in my patent, excepting that instead of the crank employed in my patent I here provide a rack-bar p3, meshing with a pinion p4, sleeved on the spindle of the tension and having fast to it a disk p14, in turn provided with a pin p15, to which is attached one end of a strap pl, running over and in contact with the hub of the tension-wheel and sustaining at its end the weight p17. 'Ihe rack-bar is pivoted at p5 to the arm w on the hub h referred to.

I prefer a rack-bar and pinion to the connecting-rod and crank shown in my patent, for the reason that it is more certain in its operation and permits of a wider range of movement for the different requirements of the machine. It is a very simple matter to remove one pinion p" and replace another, larger or smaller, but'having the same pitch of teeth.

On the barp3 is mounted an adjustable stop s, arranged to engage a stop-motion lever hg,

constructed and operating substantially as the correspondingly-lettered part shown in my patent. This lever is normally held in locking engagement with a rod h4 by a dog s3, whose arm s4 rests lightly on the thread t, so that when the latter breaks the dog s2 will move the lever 72,8 sufficiently to disengage it from the rod 71,L1 and permit the spring 7i7 on the latter to shift the belt b3 and stop the machine.

I find that in practice with a machine con- Strueted as described the thread will not wind properly, or at least it will not Wind to the best advantage when the quill is free to bear against the thread-guide with the full force of the Weight iu', and accordingly I have devised an automatic grip which relieves the pressure on the thread-guide of the surface of the quill in winding, thereby preventing the excess of friction, which would otherwise prove seriously objectionable. This automatic grip will be understood, viewing Fig. 3, where it will be seen that I have provided a nger or rod r, pivoted at r to the arm iv and held and sliding in a passage provided in a bracket r2, secured to the frame of the machine. A lever r3, freely pivoted on astud r4 and preferably provided with a roll T5 at its engaging end, rides against the finger 0', being normally held in biting engagement therewith by a spring r6' in a cup i engaging the outer free end of the lever.

Viewing Fig. 3, where the dotted line indicates the dead-center position of the lever, it will be observed that this lever r3 is ina position to always permit the finger or rod r to move upwardly, but to prevent its moving downwardly, and accordingly it will be nnderstood that the rod or finger rr is automatically gripped and held by the lever ras the thread mass increases on the quill, so that whatever outward movement is gained by the thread mass moving away from the threadguide is held, and the quill is automatically prevented from swinging back again toward the thread-guide, even to the minutest degree.

I find in practice the rapid rotation of the cop or thread mass acts to throw the spindle and mass just far enough away from the thread-guide to give the required ease' of movement, and this advantage is never lost, because the clutch fr prevents any return of the mass into close contact with the threadguide. This also prevents any rebounding of the thread mass and proves of great advantage in the practical running of the machine.

I have provided a shim-like back frs as a bearing-surface for the rod or finger r, which may be delicately adjusted by means of vthe set-screws r.

As the thread mass builds up on the quill the quill-spindle and its support swing away from the thread-guide on the main shaft as a center, and from this explanation and viewing Fig. 3 it will be readily understood that the button of the thread-guide maintains its ICO IIO

` ththread-guide it will be observed-that I path of movement approximately in the same plane relatively to and embracing the axis of the quill-spindle, and by reason of the fact that the arc of movement of the quill-spindle isat substantially the same radial distance from the main shaft as the delivery end of do not need to vary the position of the threadguide, as done in my patent above mentioned. It will also be understood that when it is desired to wind any dierent form of thread mass or to wind a cylinder it is a verysimple matter simply to loosen the clamping-bolt h2 and turn the quill-spindle in its support so as to bring the surface4 of the quill next the thread-guide into parallellism with the latter. Also it will be understood that the arrangement of parts as described enables me very readily to change the throw-cam from the cam such as shown to a larger or a smaller throwcam, as may be desired, limited only by the dimensions of the parts of the machine.

Inasmuch as the moving parts are much more compact and are simpler than those heretot'ore provided, I am enabled to run the machine at amuch higher speed and obtain a largely-increased output.

`The slide bar for the thread guide constructed as shown is kmuch cheaper, lighter,

and less liable to get out `of order than the' plate slide-bars heretofore provided.

I do not intend to limit my invention to the precise details of construction herein'shown, but contemplate various changes and modifications as coming within the spirit and scope of my invention. Some ol' these I haveindicated. t

My invention possesses further novelties, as hereinafter claimed.

It will be understood that where I have used the word preferable in this specification I mean thereby that I am not limited to certain features of construction herein shownv and described when certain other features of myinvention are being considered, and, moreover, I wish it understood that I do not limit myself otherwise than as expressed in the claims. v
